Hangers for lighting fixtures



Oct. 25, 1955 M. H. KRUGER HANGERS FOR LIGHTING FIXTURES Filed Jan. 26 1951 INVENTOR MICH EL HENRY KRUGER 4/ '5' ATTORNEY United States Patent 2,721,720 I HANGERS FOR LIGHTING FIXTURES Michael Henry Kruger, Malden', Mass., assignor to A. L. Smith Iron Company,Chelsea,Mass., a-corporatlon of Massachusetts Application January 26, 1951, Serial No.- 208,065 4 Claims. (Cl.'248' 343) This invention relates to lighting'fixtures in general, and more especially to hangers, such as disclosed in the co-pending application for Patent Ser. No. 32,333, of which the present is a divisional application.

It is anobject of the present invention to provide an improved hanger including an inverted dome-shaped'disk, means for securing the same to' the upper ends 'of curved downwardly extending supporting stems for connecting the disk to the upper wall ofa lightingfixture.

These and other features; capabilities and advantages of the invention will appear from the subjoined detailed description of a specific embodiment thereof illustrated in the accompanying drawings, in which Fig. 1 is a perspective of one embodiment.

Fig. 2 is an enlarged fragmental view partly in section of a hanger.

Fig. 3 is a section on the line 33 of Fig. 2.

In the embodiment shown there is illustrated a lighting fixture 1 having a casing 2 extending from the upper face thereof to receive a ballast housing, not shown. The cas: ing 2, see particularly Figs. 2 and 3, has an upper wall 3 which is provided with openings to receive the bushings 4 which may be secured to the ends of the stems 5. The bushings 4 in turn may be anchored and secured in place to the upper wall 3 by the screw threaded nuts 6.

The upper ends of the stems 5, in the present instance, are indented at 7 adjacent their upper circular heads 8 to be wider in one direction than the normal diameter of the stems and narrower than the normal diameter of the stems in a direction at right angles to said one direction so that after the heads 8 have been passed through the enlarged recess portions 9, the neck or indented portions 7 may slide up into the diminished recess portions 10 of the strap 11 secured in the dome-shaped canopy 12 and anchored against turning and displacement. The strap 11 is connected by any suitable means, such as the bushing 13 and nut 14, to the lower end of the conduit or the like fixed in the ceiling, and the can py 12 in turn is connected to the lower end of the bushing 13 by any suitable means, such for instance as the screw 15, extending up through the canopy 12 into the cap 16, screw threadedly connected to the lower end of the bushing 13. The strap 11 as clearly shown in Fig. 2 has its enlarged recess portions 9 in the two downwardly and outwardly flaring depending portions of the strap 11 with the diminished recess portions 10 in the upwardly and outwardly flaring portions of the strap 11 and only the diminished recess portions 10 registering with the recesses in the canopy 12.

Obviously the canopy 12, although illustrated as a domeshaped disk may assume other conformations, and the stems 5 which are curved or arcuate may assume other conformations, even straight, and the stems 5 may be connected to the casing 2 by means other than the bushings 4, without departing from the general spirit of the invention.

It is obvious that various changes and modifications may be made to the details of construction without de- 2,721,720 Fatenrtedoct. 25, ,1955
